Where is the star Sirius located?
Sirius is located in Canis Major at RA 6h 45m 08.9173s Decl -16° 42' 58.017". It is about 8.6 light years away.
How far apart are Sirius A and Sirius B?
Sirius is a binary star system Sirius A and Sirius B.The distance separating Sirius A from B varies between 8.1 and 31.5 AU. (See related question).
Is Sirius a a white dwarf?
No, but Sirius B is,
Where is Sirius b located in the night sky?
Sirius, which consists of both Sirius A and Sirius B is in the constellation Canis Major, which, if you are looking south, appears below and to the left of Orion. Sirius B itself is too dim to be seen from Earth; the vast majority of the light from Sirius is from Sirius A. Even then, as a binary system, the two stars are too close together for us to see them separately.
What is the apperant magnitude of Sirius?
Sirius is actually a binary star system. Sirius A has an apparent magnitude of -1.46 whereas Sirius B has an apparent magnitude of 8.3
What are Sirius's celestial coordinates?
The celestial coordinates of Sirius are: Right Ascension: 6h 45m 09s Declination: -16° 42' 58''
The celestial coordinates of the autumnal equinox are?
RA = 12 hours Declination = zero
When is the sun located at 6 hours RA -23.5 degrees declination?

What are the right ascension and declination of the star Sirius in the constellation Canis Major?
right ascensition and decliation orion in 2012
What is the right ascension and declination of the brightest star in the Octans constellation?
The brightest star is v Oct with an RA of 21h 41m 28.47s and declination of −77° 23′ 22.1″
What is the latitude and longitude of the constellation Pisces?
The terms "latitude" and "longitude" only apply to terrestrial navigation here on the surface of the Earth. In Astronomy, the terms "right ascension" and "declination" are used instead. The RA of Pisces is 1 hour and the declination is +15 degrees.
Where is the star Sirius located?
Sirius is located in Canis Major at RA 6h 45m 08.9173s Decl -16° 42' 58.017". It is about 8.6 light years away.
When will a star with a right ascension of 2.0 hours rise?
That depends on the date, since the sun itself moves through the entire range of RA during the year. It also depends on the star's declination. Viewed from the northern hemisphere, for example, the greater a star's declination, the earlier it rises, and if its declination is greater than the complement of the observer's latitude, then it never sets.
One hour of right ascension is equivalent to how many degrees of sky rotation?
Depends on the declination in question. There are 24 hours of right ascension in 360 degrees, so at the celestial equator (declination = 0 degrees) 1 hour of right ascension is equal to 15 degrees. But as you increase or decrease declination the right ascension lines converge to the celestial pole (like longitude lines on a globe). The angle covered by 1 hour of right ascension is therefore equal to (15 degrees x cos(declination) ), so at the celestial poles (declination = +/- 90 degrees) 1 hour of RA is 0 degrees.
What is the declination of Gemini?
The declination of the constellation Gemini is +20.
What constellation are behind Orion?
There are no constellations "behind" or "in front of" other constellations.Orion is an area of the sky (about 594 square degrees centered at 5h RA and +5° Declination).The constellations around Orion are:GeminiLepusMonocerosEridanusTaurusAuriga
What is a magnet declination?
Magnet declination is the angle between magnetic north and true north. Declination is considered positive east of truth north and negative when west.
